Answer:
const greet = ["hello", "hi"];
console.log(greet.length); // greet.length is 2
greet.push("welcome"); // Adding the element('welcome') to the array(greet)
console.log(greet); // ["hello", "hi", "welcome"]
console.log(greet.length); // Now greet.length is 3

Undefined, since the array starts from 0, and It's a total of four elements in the array.

3. undefined - because Arrays are Objects so routine[4] = 'work' will not throw an error (like in python) . And there is no routine[3] element so js will assign undefined
